They're... bleeding the prisoners... putting the blood... in those globes.
<Grumm's eyes close momentarily and he leans his head back.>
The blood... taken up to necropolis... to feed blood prince...
<Grumm gasps for breath.>
P-promise... you'll... destroy blood... globes... bring word... to Junek.
<The snow tracker collapses into unconsciousness.>
Completion
I feared they might've captured Grumm, but I never thought they'd do such horrific things to him. I've never seen a warrior survive a losing battle with the Scourge.
Thank you for bringing word of his fate, <name>. He was a mighty warrior and we will remember him as such.
